Physicists unveil new form of matter—time crystals

Normal crystals, likes diamond, are an atomic lattice that repeats in space, but physicists recently suggested making materials that repeat in time. Last year, UC Berkeley's Norman Yao sketched out the phases surrounding ...

Time crystals might exist after all (Update)

(Phys.org)—Are time crystals just a mathematical curiosity, or could they actually physically exist? Physicists have been debating this question since 2012, when Nobel laureate Frank Wilczek first proposed the idea of time ...

New liquid crystals prevent automobile touch screens from freezing

In addition to appearing in nearly every consumer electronic device, liquid crystal displays have recently proliferated in automobiles too, in heads-up displays, instrument cluster displays, navigation systems and entertainment ...

First phononic crystal that can be altered in real time

Using an acoustic metadevice that can influence the acoustic space and can control any of the ways in which waves travel, engineers have demonstrated, for the first time, that it is possible to dynamically alter the geometry ...

Physicist proves impossibility of quantum time crystals

(Phys.org) —Is it possible that a moving object could have zero energy? The common sense answer is no, since motion itself is kinetic energy, but this answer has been challenged recently by the concept of quantum time crystals. ...

Creating time crystals with a rotating ion ring

(Phys.org) —There has been a lot of talk recently about the possibility of building what has come to be known as a time crystal. In February 2012, Frank Wilczek originally proposed the idea that under certain conditions, ...

Ultra-thin transistors spread like butter on toast

Like spreading a thin layer of butter on toast, Cornell scientists have helped develop a novel process of spreading extremely thin organic transistors, and used synchrotron X-rays to watch how the films crystallize.
